Mini Air Cooling Fan works

"Mini Air Cooling Fan" rotational force energizing coil in a magnetic field. Form of energy is transformed: the main electrical energy into mechanical energy, and because the coil has a resistance, so there is inevitably a part of electrical energy to be converted into internal energy. When the fan work, due to the current through fan coil wire is resistance, so "ios版雷竞技下载 " will inevitably produce exothermic heat outward, so the temperature will rise. But why do people feel cool? Because the body's surface has a lot of sweat, when after the "ios版雷竞技下载 " Working together, the indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with "evaporation needs absorb a lot of heat, "so people will feel cool.
